In what reads like one of the biggest sour grapes lawsuits of the year, Lady Gaga's former assistant claims she was a slave to the singer, having to do such unconscionable things as fetching a towel for her after she showered, and keeping GG on schedule!

Jennifer O'Neill says in her lawsuit ... she worked for Gaga for 13 months, and is owed $380,000 in overtime. O'Neill says in her suit her job included "ensuring the promptness of a towel following a shower and serving as a personal alarm clock to keep [Gaga] on schedule."
